I don't need my boss to care about me. I need them to care about the team succeeding, and the mission I signed up to.

I need them to show some very baseline decency and honesty so that I can somewhat trust what they say. I need them to not drive their own career at the expense of the company or team.

If the company needs to do layoffs, I want them to pick the right people to stay, to have a good shot at still doing a good job, not pick emotionally.

You don't have to care about people to understand it's better to not burn them out. Staff turnover is expensive and bad for the team performance. Quality and innovation starts suffering long before people implode.
